Cannot use jira as a Confluence user server

[Martin Baltuhin]

We have 2 apps that use jira as a user server. Bitbucket to Jira whitelist works fine, same one for Confluence does not. It accepts 0.0.0.0/0 and it works, but using the Confluence host IP (with and without /32 mask) or the actual host name and both are not working. No logs are being generated from the tryouts i did.

If the Confluence system has multiple network interfaces, it's possible that it is making requests to Jira from an interface other than what the hostname resolves to. You can track this down by looking at the system routing table and seeing which interface a specific destination is directed to. In PowerShell, that's Find-NetRoute, in Linux it's ip route get.

If the system doesn't have multiple interfaces, I would need more information about the environment to comment sensibly.
